本文采用水热合成法制备了一类稀土氟化物纳米晶，其生长模式随离子半径的减小而逐渐改变，可作为研究稀土纳米晶可控生长机理的模型体系。此外，我们证明了这些纳米晶体的功能化通过掺杂，这显示了可见的肉眼绿色上转换发射，并可能在生物标记领域中找到应用。
In this paper, a hydrothermal synthetic route has been developed to prepare a class of rare-earth fluoride nanocrystals, which have shown gradual changes in growth modes with decreasing ionic radii and may serve as a model system for studying the underlying principle in the controlled growth of rare-earth nanocrystals. Furthermore, we demonstrate the functionalization of these nanocrystals by means of doping, which have shown visible-to-the-naked-eye green up-conversion emissions and may find application in biological labeling fields.
